The London-born musician, whose real name is Michael Omari, supported Mr Corbyn in his general election campaign and the politician also recently presented him with his solo artist of the year gong at the GQ Awards.

At the GQ Awards, the singer branded Prime Minister Theresa May “a paigon”, which he explained to Ross was “a snake, a foul person”.

He told Ross: “You see all this politics stuff … I think a lot of them are paigons in that sense. Let me put it like this, I remember when I was in primary school and for whatever reason at the time, I could have sworn Tony Blair was this great guy … So since then I’ve just had trust issues with them.”

The singer then jokingly issued his “warning” to Mr Corbyn, saying: “Don’t mess it up. Don’t mess it up, J!”
